These are gaiters from OUTDOOR RESEARCH. The material is waterproof and breathable, with a ripstop structure that makes them durable, lightweight, and easy to store when folded. They are a full-open type with Velcro, so you can put them on and take them off with your shoes on. The top is secured with a one-touch buckle on a nylon belt, which can be easily adjusted and will not loosen after adjustment. The bottom is secured with a fiber-reinforced nylon belt, triple-stitched to the main fabric, providing peace of mind that they can still be used for a while even if the stitching comes undone, unlike cheaper gaiters. Size is L, suitable for 26 cm to 28.5 cm. Top width when laid flat: 23 cm Bottom width when laid flat: 25.5 cm Length: 42 cm
